The 4,general object ot my present invention is to provide an improved conduit system for passingthe 'heating .gas fromV a asv producer to a. furnace or otherapparatus'in which the' gas is used. The invention com`- prises improvements in the conduits proper and inthe relative arrangementot theconduits, gas producer and the furnace or other apparatus in which the gas-is utilized, devised` .with the specilic .objects in view of providing a compact and convenient ar4 rangement of the producer, distributing conduits, and furnace or the like, whereby groundjspace vis economized While at the same time al conduit system of suthcient length is provided to efec'tially clean the gas in its passage therethrough and which may be readily cleaned trom time to time as occasion requires. Y

rl"he various features of ,novelty which characterize my invention-are pointedout .Withparticularity in theclaimsannexed fto andV forming a part of this specification. For a better understanding. of theginven-V tion,rhowever, and tlie advantages possessed by it reference',v should behad tothe accompanyingdrawings and descriptive matter in Which l have illustrated and described a preferred embodiment loitx my invention. n

@t the drawings;

posite ends ot which the sections B2V and Bt are connected by the sections B and B3, rcspectively, which bend around the producer A located between them. The ends of the sections B2 and BL remote from the producer are connected to one another by the section Which is parallel to the sect-ion B. Thilo I regard the special form of the conduit system just described, as the best form devised by me for use in a plant ot the particu lar character disclosed in detail herein, it will be obvious to those skilled in the art that my invention in certain ot its aspects is not restricted to this or any other particular conduit shape.` v

Valves or dampers C and C are employed to close communication Whenever necessary Vor desirable between the conduit section l and the conduit sections B and B3 respectively. Valvcs or dampers C2 and Caare employed toclose communication when necessary or desirable between the conduit section B5 vand the conduit sections B2 and B1' respectively. BG and B7v re iresent service outlets *opening from the conduit sections B2 and B4 respectively as shown. The invention,i\vhile applicable to gas tired `turnaces' generally,V is ot especial utility in plants in which thefurnace tired is a continuous tunnel kiln, and in t-he .plant shown the outlets BG and B7 deliver as to the combustion chambers ot' a continuous tunnel kiln H ot the Dressler type which. runs trans4 versely to the length' ot' the conduit sections and-Band is located above said sections. The two combustion chambers I are sup- Vported on the usual 'masonry benches H provided for the purpose in the mam chamber of the lriln H atopposite sides of the usual trackivay H2 :for the cars by Which ware is moved through the furnace.y One'outlet passage B6 and `one outlet passage B7 pass upward Athrough the corresponding'bench H to one of the combustion chambe I, While the other outlet. passages BG and BT pass up through the second bench l to the combustion cham ber mounted thereon.- yEach ot the outlets BG and BT is provided 'with a cut off valve or damper fi, shovvn as mounted in a hori- Zontalslideway inthe corresponding,` bench H. Air tor-the combustion ot the gas is supplied to the combustion chambers I in any usual or suitable manner. As Vshown this air is supplied to the ends of the combustion ,chambers adjacent the gas outlets -BG from the conduit sections B2 and B4 of the conduitin which it is located. Baflles F alternate with the baflies E in the conduit sections B and B3. The bailles F, each of which extends transverselyI of the portion of the conduit in which it is placed, are in the form of brick walls extending upward from the floor of the conduitapproximately halfway to the topof the latter. Clean out openings B9 are provided along the conduit sections B, B and B3 at convenient points for removal of soot, ashes or the like deposited from the gas in the conduit between the various floor arches F. Advantageously these openings B9 open into the pit in which the producer 1s located. The floor A10 of this pit may advantageously be at, or below,

the level ofthe upperside of the bottom wall of the conduit. These openings B9 are normally closed by doors Gr which may be cast iron doors of the type usually employed for such purposes.

tionB5, and, as shown, inspection pits B8 are located at the outer ends of the portions B2 and Bl in line with the section B5.

lathe normal contemplated mode of operlation ofthe apparatus shown, the dampers C and C are opemand the damper-s C2 and G3 are closed. rlhe hot @as Jassi'ne into the conduit system through the downcomer A2' .from the producer'A divides in the section B, part. passing through the Sections B and B2 to the outlets B6 and through the latter into the Vcombustion 'chamber 'I'of the kiln ll, while the remainder ofthe gas i passes through the conduit sections'Ba and Bt'to the outlets B7' and through the latter into the combustion chambers LL As the gas passes from the downcomer A2 to the outletsBC andB7 soot, ashes and tar are thrown out of the gas, the gas streams bend up and downk in passing the bailies E and F and collect on the walls, and'ipaaticularly on the bottom wall ofthe conduit. If' the conduit is suitably proportioned, the gas leaving tlie conduit'through the outlets Bx and B7 will be sufficiently cleaned. llith the' arrangement shown in which the conduit is connected to the side of the producer A remote from the furnace H, it ispossble to obtain suflicient length of conduit 1n each branch of the double connection from-the "Latinum" i n A clean out stack DV Vopens at its lower end into the conduit secproducer'to the furnace for Ieiiicient cleaning with the producer located in close proximity to the furnace thus economizing' in the use of ground space required Vfor `theplant asawhole. Y 1

VVhenit is desirable to clean out the conduit onebranch is cleaned at a time. T0 clean the branch comprising the sections B fand B2 tliefvalve C'is'closed, after which the corresponding clean out doors G Vare opened, and t-he'inat'erial deposited on the floor` of the conduit is removed through the doorways B0. When it is desired to more thoroughly clean this conduit branch, Vas may benecessary from timeto time, the

damper C2 is openedand a lireis started inl the conduit to burnout the soot and tars deposited on the Walls of the conduit, the stack D providing the necessary draft. Vln

cleaning the conduit branch comprising the sections B3 and B4, `the dampers C -and C? will be open, andthe dampers G and C2 willVY be closed. ltwill be understood, :of course, that cleaning either branch of the gas delivery conduit, the dampers K controlling the corresponding deliveryoutlet B6 or B7 will be closed. By cleaningthe conduit, one-branch'at a timeas described, the supply of gas to the furnace need never be totally interrupted, though ordinarily in a furnace of the type illustrated'something less than the full amount of gas normally supplied to f the furnace. will be given the latter Vwhen a cleaning operation is'being carried out. lf, as showin-the delivery conduit passes under furnace and all portionsof its bottom wall are at the same level, it .isnecessary tomake the bottom level of the producer'pit somewhat lower than would ordinarily be required otherwise,V but this has a compensating advantage, in that if the producer is fed at the top, asis usual, it isnot'necessary to elevate the coal fedl into the producer as high as would otherwise be required. The

formation of the deliveryfconduit with Vtvvo delivery branches B', B2, and B3- and B4.

separately connected to the combustion branches vis especially advantageous' where, as 1s frequently the caseit is desirable 'to introducecombustible gas intov eachof the;V

elongated combustion chambers at spaced apart points along' the length 'ofthe latter..` While, in accordance withV the *provisions of the statutes l have illustrated and described the best formV of my invention now chambersof a tunnel kiln crossing the two? known toV me it will be apparent to those skilled in the art that"changesv maybe Vmade in the form of the apparatus disclosed withoutdeparting from the'spirit Ofmyinvention, asset forth in the appended claims and thatcertain Vfeatures of the invention may'V Y sometimes be used to advantage'without aV corresponding use of other.- Y'
